The dc voltage across $R_L$ in a rectifier circuit is typically calculated by taking the peak voltage of the AC input (minus the diode drop, if applicable) and then considering the rectification type (full-wave, half-wave, etc.). Without seeing Figure 6, a precise calculation can't be made, but a common approximation for a full-wave rectified output is around 0.7 to 0.9 times the peak input voltage (minus diode drops). Assuming a peak voltage slightly above the RMS value (which is often around 120V or 230V in household settings, but could be different in this context), and without specific details, the closest standard answer given the typical rectification and smoothing factors would be 7.5V, suggesting perhaps a much lower input voltage or a specific context provided by the figure. This is a general explanation; the exact reasoning depends on the details in Figure 6, which are not provided.
